Higher levels of lean muscle may protect against Alzheimer’s disease
Individuals with higher levels of lean muscle may have a reduced risk of developing Alzheimer's disease. While further research is needed to understand the underlying biological pathways and implications for clinical practice, these findings shed light on the potential role of lean muscle in protecting brain health.
